    Hi,

    I've been looking into UML and qemu for virtualization and testing
    distro's and features.

    It seems to me that qemu is a nice way to testdrive a distro, upgrading,
      checking a new kernel (an issue i've been having with an upgrade from
    a woody to a sarge release), testing backups (restore). Even some
    proprietary OS runs on it (if that's an advantage, i'll leave that up to
    you :))
    Qemu is also extremely easy to setup.

    UML on the other hand seems faster and more suitable to sharing a
    machine and giving each person his/her own UML to mess with.
    What i'm planning to do in the future for my home lan is making a few
    UML's on my current server to provide different hosts for DHCP,DNS, mail
    and webserver. I can't see this happening with qemu because it would
    probably be a bit to slow.

    I haven't played with Xen or vservers yet.

    Does anybody know if it's possible for UML to install a distro from a cd
    like you can do with qemu? That way you can really test the setup of a
    distro. For instance, one could test the debian installer.

    Both for UML and Qemu what would be an good way (=easy setup) of sharing
    the package cache of the host? Ideally that would be something that can
    be used by other hosts on the LAN too.
    I'm currently having a look at apt-move

    Thanks for any remarks/comments

    Regards,
    Benedict
